Grah, sorry. That was the one where he just mentions it's not canon.

However, there are several interviews where they talk about it being in an alternate universe. There's this one mentioning something from Dengeki...

...and a lot videos (which are linked in the Primer) where it's mentioned in passing while discussing the game. I just don't feel like slogging through all of them to find it just for you..some of them are rather long.

Even without that, you have to think about how something can not be canon (as stated), and somehow still effect the canon (like you say). The fact is it can't, and if the guy writing the story and heading development of the game says it isn't canon and has no affect on the existing series, then it doesn't.

Believe what you want, but that's the truth, and I wouldn't have put it on the wiki if it wasn't something I heard/read from one of the insurmountable sources...
